I have a lot of ideas. Like, when you revive all the same kind of dead ghost, can we unlock the appearance of him? That would be very nice. Also, bring more campaign levels OR new campaign maps. Because I explored all the maps in this game, and I want more of them. AND BRING NEW PLANETS!!! Like Uranus, Jupiter or Saturn. That would be epic!!! Add new gamemodes too. Because you just have to kill aliens, go somewhere, kill aliens again, or defend a spot during a certain time. And I am sure that a lot of people want this too. So think of it, please
